We aim to develop an automatic contents production system of soccer video commentary based on digital shooting techniques, which consists of digital camera work and digital switching technique. Digital camera work is defined as virtual panning and virtual zooming. Virtual panning is a video production technique of clipping a fixed size frame and then controlling the frame location on a high definition material video. Virtual zooming is a video production technique of clipping a frame and then controlling frame size. Also, digital switching is defined as the change in virtual cameras by controlling the rapid change of frame location or size on a high definition material video. We describe a method of digital camera work that focused on players and a ball as a sub-system of an automatic contents production system for soccer video commentary. This study uses analytic hierarchy process to carry out subjective evaluation of the produced video contents with digital camera work.
